Family traveled 25 miles in 1/2 hour. If it’s currently 3:00 pm and the destination is 225 miles away, what time will they arriv

dangina [55]

It is currently 03:00 PM, the family will reach at 03:00+4.5 = 07:30 PM

Step-by-step explanation:

We have to calculate the speed first to find the time it will take the family to complete the trip.

Given

Distance = d = 25 miles

Time = t = 1/2 hours = 0.5 hours

$Speed =\frac{d}{t}\\=\frac{25}{0.5}\\=50 miles\ per\ hour$

Now,

Distance remaining = 225 miles

Speed = 50 miles per hour

$s=\frac{d}{t}\\t=\frac{d}{s}\\t=\frac{225}{50}\\t=4.5\ hours$

As we see that the time required to complete the journey is 4.5 hours.

It is currently 03:00 PM, the family will reach at 03:00+4.5 = 07:30 PM
